Just tested and it works on X. So this is Wayland specific.

Comment 2 Harald Sitter 2020-06-15 08:29:59 UTC

Moving to klipper. This is a wayland problem, though I'm not sure if it is klipper or qclipboard that's the problem here. What I see in wayland is that any copy from any app isn't persistent beyond the life time of the app and also they are not tracked in klipper.

Comment 3 Patrick Silva 2020-06-15 12:20:38 UTC

Same thing on neon unstable.

Comment 4 Claudius Ellsel 2020-08-05 22:12:09 UTC

Might have been fixed by the recent clipboard improvement for Wayland. I have not tested it, though. If you can confirm, this might be a duplicate of the relevant bug report (I guess making Klipper work on Wayland).

Comment 5 Patrick Silva 2020-08-27 14:29:43 UTC

possibly duplicate of bug 424649

Comment 6 Claudius Ellsel 2020-09-10 18:26:04 UTC

Just tested with a Plasma session compiled from master. It is still happening for me, so I assume that https://invent.kde.org/plasma/plasma-workspace/-/merge_requests/1 did not fix this.

Is this a hint that qclipboard is causing this?

Comment 7 Patrick Silva 2020-11-01 11:28:32 UTC

I can't reproduce on neon unstable.

Operating System: KDE neon Unstable Edition
KDE Plasma Version: 5.20.80
KDE Frameworks Version: 5.76.0
Qt Version: 5.15.0

Comment 8 Claudius Ellsel 2020-11-01 14:41:42 UTC

Possibly https://invent.kde.org/plasma/kwin/-/merge_requests/365 fixed this. I will add Aleix to the CC of this bug, so he can clarify.

Comment 9 Aleix Pol 2020-11-01 18:29:54 UTC

What my fix addresses is only related to xwayland. This was originally reported on 5.19 which IIRC didn't have clipboard management supported yet.

Either
https://invent.kde.org/plasma/plasma-workspace/-/merge_requests/1
or 
https://invent.kde.org/plasma/kwin/-/merge_requests/365

fixed it depending on the technologies used. It should be safe to close right now.

Comment 10 Claudius Ellsel 2020-11-02 13:27:14 UTC

Alright.

Maybe there were two different bugs at different stages of this bug causing the same symptoms.
